I THINK they are $150 an hour. LHT Performance gets a slightly different rate than the average dude. You would need to call to get pricing.
Yes they have air/fuel and its an inground dyno.

They dyno'd a Harley Davidson truck while we were there that just got a pulley and chip and some kind of air induction and it put down 480tq and 380hp....good stuff. Also Dan from Idle Wild was there with a sweet orange mustang that put down some very impressive numbers.
